Performance Improvement Program for Pumps
In an effort to improve pump performance and extend service life on old and new pumps, Belzona has developed the pump performance improvement program.
  • Performance gains range from 7% on new pumps to 40% on those in service
  • Reductions in operating costs can be realized immediately
  • Pumps protected with Belzona systems are certain to last longer
  • Belzona systems resist the damaging effects of erosion/corrosion, abrasion, and chemical attack that destroy cast iron, steel, bronze, and other materials of construction
  • Worn pump components can be easily rebuilt and/or coated at much lower cost when compared to direct part replacement
  • Ability for refurbishment of scrap components with minimal downtime
